Gradient-grade solvents are suitable for liquid chromatography. These solvents are free from UV-absorbing impurities and ensure a consistent result in gradient analysis. Gradient grade solvents have undergone additional testing relative to isocratic solvents in order to ensure a low impurity gradient LC baseline and low gradient baseline drift.

ATP analogs substituted in the gamma-phosphorus (ATPgammaS, beta, gamma-imido-ATP, and beta,gamma-methylene-ATP) were used to probe the involvement of P2 receptors in the modulation of synaptic transmission in the hippocampus, because their extracellular catabolism was virtually not detected in CA1 slices.
